Deep clean filter question

I watched the video for cleaning your filter by taking the top off and inserting the water hose, etc. It said to make sure your filter plumbing is disconnected from your pool. I left my pool open all year and everything is still connected (and I've never disconnected anything). How can I do this deep cleaning without pushing the gunk back into my pool? Could I just put the multi port valve on the "closed" setting? Or do I have to actually disconnect the pipes from the filter?

I gotta tell ya'. Deep cleaned mine last year and didn't disconnect anything. Pump won't be running anyhow. Still be a major jump in improvement even if you do have a small OOPSIE moment. One quick tip-before you ever put the hose in and gently jab it around, use your hand to scoop all you can off the top of the sand bed and the top inside lip area of the filter body itself----mine was caked! Do a good job!

I unscrewed the top part of my filter and this is what I see. What do I do at this point? I tried to unscrew this part and it does turn, but it only turns so much and it won't turn anymore. I chickened out and put everything back the way it was. Does that piece come out or do I just stick my hose in there? I certainly can't ft my hand down through there with it in there, but I could fit the hose.

The sand didn't look all that bad compared to some of the youtube videos I've seen and I don't have any problem with my filter, but I did want to understand how to do this process.

HELP?!?

The idea is to float the dirt and debris up and out of the filter by overflowing. You can't get your hand in it to stir it up? I assumed all were big enough to do that.

That just look like some kinda flange or sleeve to me to cover the stand pipe, but we need somebody with experience on that particular filter to chime in.

I googled your filter and found this image:

I then checked youtube and found a video where the guy just carefully pushed the diffuser to the side out of the way.

Hopefully this will work for you too. :thumleft:

Yeah, so I was able to move it to the side and get my hand down in there and perform the process. I wouldn't say it was a disaster, but much more than I was anticipating flowed back into my pool so I don't think i'll be doing that again unless I disconnect my plumbing from the filter.

Knowing that it's never been cleaned since I bought the house/pool over 5 years ago and likely not for many, many years prior, I decided to deep clean my Baker Hydro HRV30 sand filter. My filter has the plumbing in/out on the side and the valve (a Hayward "SP715 ALL" multiport) sits adjacent, between the filter and pump. I was able to get the top of the filter off and work my hand in around the diffuser that blocks most of the opening and worked my way thru the sand with my water hose thoroughly. I'd read about channeling in sand filters but mine was literally clumped. So I gently worked my fingers thru as much as I could reach and probed carefully with the hose to try to break up the sand. All was going pretty well, although I didn't see a lot of debris washing out and I could definitely feel a fair bit of small twig-like debris in the sand.

But I failed to consider the valve, so you can guess what was happening all this time... a fair bit of the brown, strirred-up waste water was working its way back into the pool. It's taken me 3 days to clear up the mirky mess.

I'd like to take another run at deep cleaning the sand to try to float out more of the debris, but what setting do I need to move the handle on the multiport valve to ensure that gunk I'm dislodging in the filter can't back into the pool?

And, is there a point where the sand is so corrupted by debris that you hafta consider replacing it? The opening of the filter is obscured by the diffuser so I really can't see down in there, but it feels like there must be a lot of foreign matter in the sand. Also worth mentioning that when the timer kicks the pump on, there's usually a small dusting of very fine sand or silt that shoots out of the 2 (of 4 total) returns nearest to the pump.

On that Baker sand filter, does anyone know how to remove the diffuser to have better access to the sand? Just opening the thing up was a fairly bold step for me! This filter is extra intimidating because of the additional interior plumbing bits that are not typical of the sand filters with top-mounted valves featured in the YouTube videos.
